1 / 8 page Part # Description M-985-01P 22-pin plastic DIP M-985-01S 20-pin plastic SOIC M-985-01T 20-pin plastic SOIC,Tape and Reel www.clare.com DS-M985-01-R1 M-985-01 Precise Call Progress and Special Information Tone Generator 1 Features • Precise detection of call progress tones • Linear (analog) input • Digital (CMOS compatible), tri-state outputs • 22-pin DIP and 20-pin SOIC • Single supply 3 to 5 volt (low power CMOS) • Inexpensive 3.58 MHz crystal time base • Wide dynamic range (30 dB) • Lower power consumption (power-down mode) • 425 Hz detection • Special Information Tone (SIT) Detection Applications • Automatic dialers • Dialing modems • Traffic measurement equipment • Test equipment • Service evaluation • Billing systems Description The M-985-01 is an integrated circuit precise tone detector for call progress and special information tones (SIT), as defined by CCITT. The use of integrated circuit techniques allows the M-985-01 to pack the eight filters for call progress detection into a single 22-pin DIP or a 20-pin SOIC. A 3.58 MHz crystal-controlled time base guarantees accuracy and repeatability. The M-985-01 combines the call progress detection of the M-982-02 and the SIT detection of the M-984-02. It has an operating voltage range down to 3V. It has low power consumption under normal operating con- ditions. A power down (PD) feature is provided to fur- ther reduce power consumption when inactive. Block Diagram Pin Diagram Ordering Information |
